KGW Isotherm F0-C Borosilicate Dewar Flask with Flat Bottom for LN2 Storage

The KGW Isotherm F0-C is a laboratory-grade Dewar flask engineered for efficient storage and cooling of small samples using liquid nitrogen (LN2), dry ice (CO2), or other cryogenic refrigerants. It is widely used in biotechnology, molecular diagnostics, and bioprocessing applications requiring controlled low-temperature environments.

• Constructed with a flat bottom design, it facilitates stable placement on laboratory surfaces and compatibility with magnetic stirrers for continuous sample agitation.
• The vessel features a durable borosilicate glass 3.3 interior, ensuring chemical inertness and thermal shock resistance essential in synthetic biology workflows and biopharmaceutical production pipelines.
• The antimagnetic aluminum cover minimizes interference during sensitive biological experiments involving electromagnetic fields.
• Maximum liquid nitrogen capacity is 200 mL, with an evaporation rate of 0.3 L/day, optimizing cryogen usage for efficient sample preservation and short-distance internal transport.
• Internal chamber dimensions measure 40 mm diameter x 170 mm height, with overall dimensions of 63 mm diameter x 215 mm height, supporting compact integration into existing laboratory setups.

This Dewar flask is critical in live-cell imaging, cryopreservation, and cell culture storage protocols, widely adopted by researchers requiring reliable, low-temperature sample handling solutions in clinical diagnostics and biomedical engineering laboratories.
